Serial No. 412,610.

easily manipulated to stack the hay or straw and in which the baby 7teeth or shorter back teeth of the fork or rake are made adjustable asto their pitch relatively to the longer or main teeth to insure the easyand timely delivery or discharge of the load therefrom.

With the above and other objects in view, the nature of which will fullyappear as the description proceeds, the invention consists in the novelconstruction, combination and arrangement herein fully described,illustrated and claimed.

In the accompanying drawings z-Figure 1 is a plan view of the haystacker embodying the present invention. Fig. 2 is a. verticallongitudinal section through the same. Fig. 3 is a detail side elevationof the connection between the baby teeth and the arms of the rake orfork. Fig. et is a detail plan view showing the manner of adjusting andholding the baby teeth.

The stacker comprises a suit-able base consisting of longitudinaltimbers or runners 1 connected rigidly by cross-bars 2 at intervals, anddiagonal braces 3 and 11 which connect the side timbers or bars 1 andone or more of the cross bars 2, thus forming a stout rigid frame onwhich the remainder of the stacker mechanism is mounted. y

Extending up from thel base frame at opposite sides are inclined posts 5between which and the side bars are braces 6, the latter also formingsupports for the bearings of a drum or windlass 7, hereinafter moreparticularly described.

Pivotally connected to the posts 5 at the points 8, are oppositelyarranged stacker arms 9. The opposite or free ends of said arms carrythe stacker rake or fork which comprises the main fork member embodyingthe longer teeth 10, and the back fork member 11 embodying the shorteror baby teeth. The longer teeth 10 are secured together by y a pluralityof cross bars 12 and 13 and also fastened to the arms 9 to movetherewith. 4rl`he shorter teeth 11 are secured vtogether by one or morecross bars 13 and said smaller rake or fork member is connectedpivotally at 14 to the other fork member.

. A brace 15 is pivotally connected at one end to the smaller forkmember 11 and has its opposite or rear end also pivotally connected to asegmental link 16 in the form of a horseshoe, as best illustrated inFig. 3, it being noted that one end of the link is connected to thebrace 15 while the other end thereof is pivotally connected to theadjacent arm 9. It will be understood that two braces 15 are employed,one in connection with each stacker arm 9, and a pair of segmental links16 are used in connection with Y each brace to straddle the brace andstacker arm and prevent relative lateral play or looseness between saidparts. It is important to obtain a firm connection at this point onaccount of the fact that when the rake or fork is elevated the weight ofthe load is transferred from the teeth 10 to the teeth 11 and the lattermust be supported by the braces 15. Flexible stay straps 17 are' secured`to the lower ends of the braces 15 and provided with slots 18 whichreceive clamps, preferably in the form of bolts 19 on the stacker arms9, whereby the braces 15 may be held when adjusted. By the meansdescribed the smaller member of the rake or fork may be adjusted as toits angle to the main member to cause the load to slide easily therefrom-When the fork or rake is elevated to discharge its load. 2O designatesdiagonal braces between the arms 9 and the main fork or rake member.

Connected pivotally at 21 to the base frame is a crane comprisingupwardly converging arms or side bars 22 and top cross bar 23 connectingthe same. Rods 24 extend from the arms 9 upward to the top bar 23, andwinding connections 25 run from said top bar around the shaft 26 of thedrum 7 said connections winding on the shaft 26 at opposite sides of thedrum as shown in Fig. 1. An operating connection 26a is attached to thedrum and is wound thereon and leads forward under the rake or forkthrough one or more guide eyes 27 to be within convenient reach of theoperator who by pull- -ing on said connection may hoist the load of hayor straw and cause the fork to deliver the same upon the stack.

draft animal may be hitched to the opera-ting connection 26 to performthe Work. The base frame of the stacker may rest on the ground or besupported on carrying Wheels as may be found expedient.

I claim A stacker comprising a base, stacker arms, having a jointedconnection at oneend there-v with, means for raising and lowering saidarms, and a rake embodying two pivotally related members one of-Which 1sfastened to the stackerV arms, braces connected pivot-ally to the othermember, segmental links connected at one end to the braces and at theother e'nd to the stacker arms, slotted stay straps connected to saidbraces, and clamping means for fastening said braces when adjusted.

In testimony whereof I aiix my signature in presence of two witnesses.
